The rear muffler defines the MPI Automotive SSMKTY0404: it's the quietest-mannered of the 3in turbo-back builds for the Toyota Landcruiser GDJ79 2.8L turbo-diesel ute (2023 on), and the only one here that keeps both the catalytic converter and a full muffler. For a 79 Series that works hard but still does long highway hauls, it's the version that won't drone you into the ground.
Why is the muffler build the easy-living choice?
A muffler absorbs and chambers sound rather than letting it pass, so the SSMKTY0404 is the most subdued GDJ79 turbo-back on offer. You still get the open 3in run from the turbo back, but the muffler tames the four-cylinder diesel's note for towing days and long touring legs where constant boom gets tiring. It's the pick for owners who want flow without turning the cab into an echo chamber.
What does keeping the cat mean for compliance?
Unlike the cat-delete builds in this family, the SSMKTY0404 retains the catalytic converter — it keeps the emissions hardware the ute left the factory with, which is the usual sticking point on a modern diesel ute. That doesn't make it automatically road-legal: the rear-section change affects noise and routing, so confirm the exact build and any state requirements with the workshop before fitting.
Where does a 3in turbo-back sit on the GDJ79?
Turbo-back means the system is replaced from the turbo outlet rearward, a longer span than a rear-section swap, sized at 3in for the 2.8L turbo-diesel. On a ute that tows and works on dirt, the run is built to keep gas moving from the turbo back. Stainless construction gives it the corrosion life a working Landcruiser needs, at an RRP of $3,631.01 — the dearest in this turbo-back group, reflecting the cat and muffler hardware retained.
